enable storage failed

Failed to execute microk8s enable storage Output is as follows

Enabling default storage class. 
sudo: unable to dlopen /usr/libexec/sudoers.so: (null). 
sudo: fatal error, unable to load plugins. 
Failed to enable storage

I have made sure that the sudoer.so library can be loaded using dlopen in c++ and the sudo command works fine.

Wish for your help!!!

Ok thanks. I think the script enable-storage.sh isn’t taking the system LD_LIBRARY_PATH like it is done for other enable script.

The enable-storage.sh should be using this [1], instead of just calling sudo. Thanks for reporting this.

For the meantime, to enable the storage, Create the directory where the hostpath will keep the images.

$ sudo mkdir -p /var/snap/microk8s/common/default-storage

Then apply the manifest below.

1. The nodename has changed from localhost to VM_67_201_centos.
2. Can you set the hostname to all small letters vm_67_201_centos

Stop and start microk8s.
